的英文介绍：

J-Series Ultraviolet Meters
The J-Series UV meters are photovoltaic devices for taking accurate and repeatable readings of UV light sources in either the 365nm or 254nm UV range.

Main Features
J-225 Meter measures the intensity of shortwave UV (254nm). Each meter comes with a sensor, attenuation screen and filter. This meter's sensor is sensitive within a range from 220 to 280nm with maximum sensitivity at 254nm
J-221 Meter measures the intensity of longwave UV (365nm). The sensor is sensitive from 300 to 400nm with a peak sensitivity at 365nm. J-221 Meter complies with MIL STD 45662-A and can be found in MIL-I-6868D (NSN 6635-488-5451)
Each meter features two scales for low and high intensity readings
For remote readings, a four foot (1.2m) cord connects the sensor to the meter
Two scales measure a wide range of intensity
An infrared filter assures accurate readings when measuring light sources producing infrared radiation
The 5X attenuation screen can be used for very high intensity lamp measurements
Meters are self-powered for maximum portability
